WAVETEK 4920 Alternating Voltage Measurement Standard

The Wavetek 4920 Alternating Voltage Measurement Standard is designed to replace the traditional AC/DC Thermal Transfer Standard in high-accuracy AC measurement applications. Fully traceable measurements can be made with uncertainties equal to or better than all but the most specialized standards with the speed, ease of use, and convenience of a single, programmable, intelligent device. AC Voltage; Ranges: 3 mV to 1000 V in 3, 10, 30 sequence. Resolution: 100 nV, 71/2 digits. Operating Range: From 30% to 110% of Nominal Range Value. Remote Programming: IEEE-488.2. Options; 10: 3 mV to 100 mV Ranges. 50: Wideband Module to 50 MHz.

Crest Factor
Crest factor or peak-to-average ratio (PAR) is a measurement of a waveform, calculated from the peak amplitude of the waveform divided by the RMS value of the waveform

Linearity is the relative difference between the displayed power ratio, Dx/D0, and the actual (true) power ratio Px/P0 caused by changing the displayed power level from the reference level, D0, to an arbitrary displayed level, Dx.

Phase Noise
Phase noise is the frequency domain representation of rapid, short-term, random fluctuations in the phase of a waveform, caused by time domain instabilities. Phase noise (L(f)) is typically expressed in units of dBc/Hz, representing the noise power relative to the carrier contained in a 1 Hz bandwidth centered at a certain offsets from the carrier.

Sensitivity is the minimum magnitude of input signal required to produce a specified output signal having a specified signal-to-noise ratio, or other specified criteria.
